Introduction
Sony started small with the E-series and hasn’t tried anything crazy since but the entry-level lineup is in its fourth generation now and offering quite a bit of choice to the budget-conscious buyer. Of course, everything you get in this price range requires a certain trade-off.
The Xperia E4 is a simple and affordable package that gives up the LTE connectivity of the predecessor but offers a 5″ screen in return. The resolution gets a welcome though inexpensive boost and the best thing is that nearly all the extra screen real estate comes at the expense of bezel in the Xperia E3. The downside is the Xperia E4 is quite chubby at 10.5mm, tangibly thicker than the E3.
Well, at 130 euro or practically free on contract, this may not be a big deal. Here’s what else you get.

The Xperia E4 is powered by a MediaTek MT6582 chipset with four Cortex-A7 cores, clocked at 1.3GHz and a Mali-400MP2 GPU, and comes with 1GB of RAM. This is essentially a mid-range chip form a generation ago and its age is starting to show.
That said, anything above 540 x 960 pixels would’ve been quite a burden for the CPU. The goal was obviously for the Xperia E4 to not feel as a downgrade. The qHD five-incher has the same ppi as the 4.5″ FWVGA screen of the Xperia E3.
Speaking of, the camera setup is nothing special with 5MP stills and 1080p video on the main unit, but the 2MP/720p selfie cam is a welcome improvement over the VGA front-facer of the Xperia E3. You do get double the storage out of the box at 8GB. There’s a microSD card slot too, of course.

The Xperia E4 will be available globally, perhaps its single-SIM and dual-SIM versions targeting different markets. We spotted the LTE-capable Xperia E4g at the MWC, trading off – there we go again – some screen diagonal for fast network data. That one too has a dual-SIM option.
All of them are entry-level offerings, meaning the competition may range from Android One phones in emerging markets to Meizu’s and Xiaomi’s in both Asia and Europe. Sony’s most important target however is probably Microsoft’s entry-level lineup, the likes of the Lumia 535.

Design-wise, the phone bears a lot of signature Sony elements, but does not offer anything special in the way of materials and is kind of bulky. It runs Android 4.4.4 out of the box, contrary to previous rumors of Lollipop. Sony recently made it clear that focus will be on the Z-series, leaving any other unlucky lineups stuck on KitKat for the time being.

For the first time in a couple of generations, Samsung is relying solely on its own Exynos platform. This seemed like of nick-of-time decision amid rumors of cooling issues and thermal throttling plaguing the Snapdragon 810 chipset but the fact is the Exynos 7420 (7 Octa) is simply better. The only reason Qualcomm were in the story at all was the uncertainty whether Samsung would be ready for mass production with its own chipset.

Built on a 14nm process, Samsung’s chipset allows similar or higher clockspeeds (hence performance) with less power consumption, which by the way means it’s easier to cool as well. In the end, the Galaxy S6 is powered by a beastly octa-core processor with four Cortex-A57 cores ticking at 2.1GHz and four Cortex-A53 “efficiency” cores at 1.5GHz. An octa-core Mali-T760 GPU and 3GB of RAM complete the tally.

Samsung worked on the camera department too, equipping the Galaxy S6 with a 16MP rear camera with optical image stabilization and a wide f/1.9 aperture. The 5MP selfie cam also got a f/1.9 aperture for superior low-light capabilities.

The connectivity package is better than ever with dual-standard wireless charging support out of the box, Samsung Pay, a better and faster fingerprint scanner and LTE Cat.6 connectivity. Let’s get into the details, shall we?

Main disadvantages

No water or dust protection

Rather pricey at launch, including really steep memory upgrade premiums

No user-replaceable battery

No microSD slot

No FM radio

No stereo speakers

Last season, the water and dust protection was a direct response to Sony’s Xperia Z line. The Galaxy S6 gives it up, defying a natural Samsung instinct to match and beat every feature a potential rival may have. A Galaxy S6 Active will likely quell some of the disappointment.

The Honor 6 comes in an understated all-glass body that could have easily carried an Xperia badge. Speaking of, Honor is the only sort of branding and the Huawei logo is nowhere to be seen. Whatever marketing strategies are at play, the company’s expertise is undeniable and is surely carried over to the Honor 6.

Just because the Honor 6 isn’t readily identifiable though, doesn’t mean it’s not well built. Actually, if you manage to keep it clean, it’s quite a looker.

Yet, its focus is clearly elsewhere. The device is aiming for a top spot on the bang-for-your-buck chart and on paper its outlook is promising. The phone packs a powerful home-brewed Kirin 920 chipset with an octa-core processor, backed up by an ample 3GB of RAM. You get a 5″ display which some consider the limit for pocketability, and it’s also a FullHD panel, so everything should be tack-sharp.

Imaging is duly covered both back and front. A 13MP main camera with dual-LED flash for the major photography occasions is backed by a 5MP wide angle font-facer for the selfies that just have to be posted and shared. Another solid spec is the battery capacity, where Huawei claims the 3100mAh unit will keep the Honor 6 going for two full days.

Key features

5.0″ 1080p display for a crisp 445ppi density

HiSilicon Kirin 920 chipset

Octa-core processor built on the big.LITTLE architecture with four 1.7GHz Cortex-A15 performance cores and four 1.3GHz power-efficient Cortex-A7′s, Mali-T628 MP4 GPU

Flagship-grade 3GB of RAM

16/32GB of built-in storage, expandable via microSD up to 64GB

Extensive connectivity options, including cat. 6 LTE for download speeds up to 300Mbps

13MP main camera with dual-LED flash and 1080p video

5MP front shooter, 720p for video calls

3,100mAh battery capacity

FM radio

Android 4.4.2 with EmotionUI 2.3

Adequate build, at 130g very light for a 5-incher with such battery capacity

Main disadvantages

No Lollipop at launch

Non-removable battery

All-glass body is a fingerprint magnet

Basic retail package

The above list points to a rich and balanced package with no major flaws to speak of – except perhaps the OS version but that’s mendable. The hardware is well-thought of and promises solid performance, hard to match in a device costing €300/$340. While the battery may not be user-replaceable, its high capacity should offset that shortcoming. And the other disadvantages clearly fall in the “minor niggle” category.

Sony Tablet Z4

Introduction
Mobile World Congress is well under way and we stopped by Sony’s stand to play around with whatever the Japanese company had prepared for us. We weren’t disappointed, even though the tech giant had decided to postpone the launch of the Xperia Z4 high-end smartphone.

Sony instead pulled the wraps off its new generation full-scale slate, the 10.1-inch Xperia Z4 Tablet. It is stunningly thin and light, features a sharp Retina-grade IPS panel, and retains the isolation from the elements, which has become synonymous with the Sony lineup. The tablet is also equipped to be a strong performer and packs innards, worthy of its flagship designation.
The Xperia M2 Aqua introduced IP68 certification to the budget-conscious crowd only a few months ago. The Xperia M4 Aqua, which Sony just unveiled, comes with markedly better hardware, including an HD display, 64-bit Snapdragon chipset and twice as much RAM.
Sony brought a bunch of accessories as well, most notably a Bluetooth keyboard dock for the Xperia Z4 Tablet, which turns it into an Android ultrabook. A quirky wireless speaker was revealed too alongside a new wireless headset. Fans of wearables weren’t left out either, and two more strap options for the SmartWatch 3 were released.
Join us on the following pages where we share our first impressions with all of the above.

Introduction
LG held a low-key event on which it announced probably the best smartwatch yet (the first with LTE connectivity to boot) and two pairs of Android Lollipop phones – one pair curved and semi-premium, while the other is more traditional.

The LG Magna and LG Spirit are slightly curved – nowhere near the G Flex2 curvature, but enough to look cool and bring you bragging rights. The Magna has a 5″ screen and a good 5MP selfie camera, while the Spirit is more compact with a 4.7″ screen. Both have optional LTE connectivity.
The LG Leon and LG Joy are straight as a ruler and are smaller, 4.5″ and 4″ respectively, but both keep the quad-core processors and LTE connectivity of their other two siblings.

The LG Watch Urbane comes in two versions. One has LTE connectivity and NFC-based mobile payments. This one runs on a new LG Wearable Platform. The non-LTE version is thinner and much lighter and while it doesn’t support mobile data or payments, it runs the more popular Android Wear OS.
